A web application that visualizes Codeforces competitive programming user data via the official Codeforces API. It provides charts of verdicts, languages, tags, and rating timelines, plus side-by-side comparison of two users.
Use cases
- visualize my codeforces submission statistics
- compare two competitive programmers' ratings
- see which problem tags I solve most
- track my codeforces rating history over time
- find unsolved problems on codeforces
- show a heatmap of my daily submissions
When to choose
- you want quick charts of a Codeforces user's performance without setup
- you need head-to-head comparison of two competitive programmers
- you want a hosted tool with no login required
When to avoid
- you need analytics for judges other than Codeforces
- you need offline or API-independent operation
- you require a maintained library with a license for embedding
